      Description

      Starting from this commit :

      LUCENE-5666: get solr started
      git-svn-id: https://svn.apache.org/repos/asf/lucene/dev/branches/lucene5666@1594254 13f79535-47bb-0310-9956-ffa450edef68

      https://github.com/apache/lucene-solr/commit/1489085807cb10981a7ea5b5663ada4e3f85953e#diff-5ac9dc7b128b4dd99b764060759222b2

      It is not possible to use Term Enum as a faceting method, for numeric and single valued fields ( org.apache.solr.request.SimpleFacets ) .

      We personally verified that there are use cases when this is bringing a quite big performance regression ( even with DocValues enabled) .
      In the mailing list from time to time people complain about a regression happening with the term enum method, but actually it is more likely to be the automatic forcing of FCS.

      Forcing FCS in co-op with the famous regression that happened in SOLR-8096 could be confused as a term Enum regression.
